Cards with Upside-down backs >>>>>> Is this a corrected error?

Hi guys,
I recently bought a 1956 Topps #1 William Harridge SGC 80 I am very pleased with the card (and even more pleased by the price) and I just noticed that the back is upside-down. Is this normal for this set? This is the first time I noticed an upside down back for a Topps card (I know there are plenty of pre-war cards with this error). I was just wondering, are there any regular issue Topps cards with upside down backs? and is this normal for this card or is this an error?
Thanx,
Jason
